According to Activision’s internal estimates, worldwide sales for Infinity Ward’s wildly popular shooter Call of Duty: Modern Warfare 2 have now passed $1 billion.

"Call of Duty: Modern Warfare 2 has exceeded our expectations and shattered theatrical box office and video game records," said Activision Blizzard CEO Bobby Kotick in a statement released to the press. "There are only a handful of entertainment properties that have ever reached the $1 billion mark, which illustrates the power of the Call of Duty franchise and mass appeal of this game."

The announcement isn’t all that surprising considering the game has been smashing sales records since it took in an estimated $550 million worldwide just five days after its release back in November, but it’s still mighty impressive.
